Device for unspooling and spooling materials in tape form, of the type comprising a pay-out spool and a take-up spool, mechanically connected together so that any rotation of one induces a rotation of the other. It comprises a take-up spool 5 and means, such as roller 9, pulley 10, wheels 15, 16 and belt 13, for driving the said spool as a function of the linear run-off (unwinding) speed of the tape. The invention can be used to increase the storage capacity of small, thermal or matrix, printers.

Description

La présente invention concerne les dispositifs pour débobiner et embobiner des matériaux en ruban, du type comprenant une bobine émettrice et une bobine réceptrice mécaniquement liées entre elles de manière à ce que toute rotation de l'une induise une rotation de l'autre dans un rapport donné.The present invention relates to devices for unwinding and rewinding ribbon materials, of the type comprising a transmitting coil and a receiving coil mechanically linked together so that any rotation of one induces rotation of the other in a relationship given.

Dans les dispositifs connus de ce genre, tels que les dévidoir.In known devices of this kind, such as the reel.

la bobine réceptrice est généralement liée à un axe moteur.the take-up reel is generally linked to a motor axis.

Cette necessité d'un apport d'énergie propre au dispositif fail qu'il est difficilement adaptable sur de petites imprimantes, et notamment celles du type à aiguilles ou thermiques, pour en augmenter la capacité de sotckage.This need for a specific energy supply to the device fail that it is difficult to adapt to small printers, and in particular those of the needle or thermal type, in order to increase the packaging capacity.

En effet ce type d'imprimantes est généralement utilisé dans de petits appareillages autonomes dont les sources d'énergie sont limitées.Indeed this type of printers is generally used in small autonomous apparatuses whose energy sources are limited.

Le dispositif selon l'invention a pour but d'éviter cet inconvénient. Dans celui-ci en effet la bobine réceptrice n'est pas entrai née en rotation constante par une source d'énergie extérieure et le dispositif se caractérise en ce qu'il est prévu des moyens pour entrainer ladite bobine en fonction de la vitesse linéaire de déroulement du ruban.The purpose of the device according to the invention is to avoid this drawback. In this latter, in fact, the receiving coil is not driven in constant rotation by an external source of energy and the device is characterized in that means are provided for driving said coil as a function of the linear speed of unwinding of the ribbon.

Ces moyens consistent en un dispositif de prise de mouvement sur le ruban, au niveau de la bobine débitrice, qui transmet mecaniquement ce mouvement sur l'axe d'entraînement de la bobine réceptrice. Ce dispositif est avantageusement réalisé au moyen d'un galet palpeur, maintenu au contact du ruban et dont la rotation est transmise, au moyen d'une courroie et d'une poulie sur l'axe porteur de la roue réceptrice.These means consist of a movement taking device on the ribbon, at the level of the supply reel, which mechanically transmits this movement on the drive axis of the take-up reel. This device is advantageously made by means of a feeler roller, held in contact with the ribbon and the rotation of which is transmitted, by means of a belt and a pulley on the carrying axis of the receiving wheel.

En jouant sur les diamètres du galet et/ou de la poulie, on s'arrange pour que le déplacement angulaire de la bobine réceptrice soit suffisant pour maintenir constamment une lé- gère tension sur le ruban. L'effet de friction, nécessaire à ce montage, est obtenu par le glissement relatif du galet palpeur sur le ruban, au niveau de la bobine émettrice sur laquelle il prend appui.By adjusting the diameters of the roller and / or the pulley, it is arranged so that the angular displacement of the take-up reel is sufficient to constantly maintain a slight tension on the ribbon. The friction effect, necessary for this mounting, is obtained by the relative sliding of the feeler roller on the ribbon, at the level of the emitting coil on which it is supported.

Le dessin annexé illustre, à titre d'exemple, un mode de réalisation conforme à la presente invention. The accompanying drawing illustrates, by way of example, an embodiment in accordance with the present invention.

Le but du dispositif est d'accroître la capacité de stockage d'une imprimante 1. Pour ce faire, le ruban de papier 2 issu d'une bobine débitrice 3, montée libre sur un axe 4, est engagé autour du cylindre moteur 11 de l'imprimante. A sa sortie de l'imprimante, le ruban de papier est raccordé à une bobine réceptrice 5, solidaire en rotation d'un axe 6. Les axes de ces bobines sont parallèles entre eux, fixes par rapport à un bâti 7, supportés par des paliers amovibles ou montés en porte-à-faux de façon à laisser libre une de leurs extrêmités, pour permettre la mise en place et le retrait des bobines. Un galet 9 est monté tournant sur un bras oscillant 8.The purpose of the device is to increase the storage capacity of a printer 1. To do this, the paper tape 2 from a supply reel 3, mounted freely on an axis 4, is engaged around the engine cylinder 11 of the printer. On leaving the printer, the paper tape is connected to a take-up spool 5, integral in rotation with an axis 6. The axes of these spools are mutually parallel, fixed with respect to a frame 7, supported by removable bearings or cantilevered so as to leave free one of their ends, to allow the establishment and removal of the coils. A roller 9 is mounted to rotate on an oscillating arm 8.

Ce bras peut pivoter autour d'un axe 10. Un ressort de traction 12, fixe d'une part sur le bras de levier et d'autre part sur un point fixe 71 du bâti, maintient le galet 9 en pression sur la bobine débitrice 3. Le galet est pourvu d'une gorge dans laquelle circule une courroie élastique 13, reliant ledit galet à une poulie 14, pouvant tourner librement autour de l'axe 10.This arm can pivot around an axis 10. A tension spring 12, fixed on the one hand on the lever arm and on the other hand on a fixed point 71 of the frame, keeps the roller 9 under pressure on the supply reel 3. The roller is provided with a groove in which an elastic belt 13 circulates, connecting said roller to a pulley 14, which can rotate freely around the axis 10.

Pour des raisons cinématiques, et sans pour autant sortir du cadre de l'invention, l'axe 10, qui n'est pas celui de la bobine réceptrice, est disposé entre les bobines et est paral lèle aux axes desdites bobines. La poulie 14-est solidaire d'une roue dentée 15, elle-même en prise avec une seconde roue dentée 16 fixée sur l'axe tournant 6 de la bobine réceptrice.For kinematic reasons, and without departing from the scope of the invention, the axis 10, which is not that of the receiving coil, is arranged between the coils and is parallel to the axes of said coils. The pulley 14-is integral with a toothed wheel 15, itself engaged with a second toothed wheel 16 fixed on the rotating axis 6 of the take-up reel.

Lorsque le cylindre moteur 11 de l'imprimante entraîne le rouleau de papier dans le sens des flèches f, le galet 9, au contact de la bobine 3, tourne par l'intérmédiaire de la courroie B, ce qui a pour effet, au moyen des roues 15 et 16, de faire tourner la bobine réceptrice dans le sens de la flèche
F, correspondant à l'enroulement du papier sur ladite bobine.When the engine cylinder 11 of the printer drives the paper roll in the direction of the arrows f, the roller 9, in contact with the spool 3, rotates by means of the belt B, which has the effect, by means of wheels 15 and 16, to rotate the take-up reel in the direction of the arrow
F, corresponding to the winding of the paper on said reel.

Pour que cet enroulement soit efficace et pour donner une légère tension au ruban, on fait en sorte que la vitesse angulaire de la bobine réceptrice 5 soit supérieure à la vitesse angulaire de la bobine débitrice 3 et ce, quels que soient les diamètres respectifs des rouleaux de papier sur les bobines 3 et 5. Cette dernière condition peut indifféremment être obtenue de plusieurs façons - Si les roues 15 et 16 sont identiques, c'est-à-dire leur rapport de transmission égal à UN, il suffit que le diamètre extérieur de la courroie sur le galet 9 soit supérieur au diamètre de la poulie 14 ou encore que le diamètre de ce galet 9 soit inférieur au diamètre initial d'enroulement du ruban sur la bobine réceptrice. Il est également possible de faire en sorte que la roue 15 ait un nombre de dents supérieur à celui de la roue 16 solidaire de l'axe 6 sur lequel est montée la bobine réceptrice 5.For this winding to be effective and to give a slight tension to the ribbon, we make sure that the angular speed of the take-up reel 5 is higher than the angular speed of the take-up reel 3, whatever the respective diameters of the rolls paper on coils 3 and 5. This last condition can be obtained in several ways - If the wheels 15 and 16 are identical, that is to say their transmission ratio equal to UN, it is sufficient that the outside diameter of the belt on the roller 9 is greater than the diameter of the pulley 14 or that the diameter of this roller 9 is less than the initial diameter of winding of the ribbon on the take-up reel. It is also possible to ensure that the wheel 15 has a number of teeth greater than that of the wheel 16 secured to the axle 6 on which the take-up reel 5 is mounted.

Dans tous les cas de figure, le glissement de la courroie 8 sur le ruban de papier, au niveau de la bobine 3, fait office de friction pour assurer la tension du papier tout en évitant sa rupture à la traction.In all cases, the sliding of the belt 8 on the paper tape, at the level of the spool 3, acts as friction to ensure the tension of the paper while preventing it from breaking under tension.

Le dispositif objet de l'invention peut être facilement adapté sur les imprimantes1 des petites machines comptables par exemple, pour augmenter leur capacité de stockage en ruban de papier, sans nécessiter une source d'énergie complémentaire. The device which is the subject of the invention can be easily adapted on the printers1 of small accounting machines for example, to increase their storage capacity in paper tape, without requiring an additional source of energy.
